Delete all duplicate elements from a set (leave unique). \newcommand{\gexp}[3]{#1^{#2 #3}} Delete the "default" expression in the textbox of the calculator. The last checkbox "Include Empty Elements" can be very helpful in situations when the set contains empty elements. As you can see from this example, the Cartesian products and do not contain exactly the same ordered pairs. For example, if the set A is {0, 1, 2}, then its cardinality is 3, and the set B = {a, b, c, d} has a cardinality of 4. Here (a, b, c) is called an Delete the "default" expression in the textbox of the calculator. \newcommand{\Tu}{\mathtt{u}} Notice that there are, in fact, \(6\) elements in \(A \times B\) and in \(B \times A\text{,}\) so we may say with confidence that we listed all of the elements in those Cartesian products. We continue our discussion of Cartesian products with the formula for the cardinality of a Cartesian product in terms of the cardinalities of the sets from which it is constructed. ], \(\left(\text{a}, 1\right), \left(\text{a}, 2\right), \left(\text{a}, 3\right), \left(\text{b}, 1\right), \left(\text{b}, 2\right), \left(\text{b}, 3\right), \left(\text{c}, 1\right), \left(\text{c}, 2\right), \left(\text{c}, 3\right)\), \begin{equation*} \end{equation*}, \begin{equation*} \newcommand{\id}{\mathrm{id}} , 3} { Apply the set cartesian product operation on sets A and B.
